Balloon Reasoning BW
1 According to the action-reaction law, if one object puts a force on a second object, the second object puts a force back on the first.
2 Since the balloon got smaller and moved, the balloon put a force on the air inside it forcing the air out and the air put a force back on the balloon according to the action-reaction law.
3 Therefore the force the air put back on the balloon cause it to move and exhibited the action-reaction law when the balloon was released.
